Has anyone attended GrayCampus Classroom Training in India?

Hello people,
(I am a beginner. I have 5 years of work experience in IT sector.)
I was recently looking out for PMP classroom training and I stumble upon the cheapest training by GrauyCampus (https://www.greycampus.com/pmp-training-instructor-led) at around 12500 Indian Rupees (~160 USD).

Can anyone please prvide the feedback if it is worth investing or not?

My Other plans are:
1. Self study with Rita Mulcahy 9th Ed
2. PM Prepcast Training + Simulator by Cornelius Fitchner (22000 INR)
